[esp-r] Re: PCM

Hi Helia,

For simulation and results analysis:
Please follow the steps below:
From:  
brows/edit/simulate menu------Actions menu----- select
simulation
from simulation controller menu -----chose integrated
simulation(from here you can adjusting  the
simulation starting and ending time and also the time step for simulation (summer
/ winter/period) or keep it as default ---chose run silently for fast
simulation 
 
brows/edit/simulate menu------Actions menu----- select results
analysis
Results analysis-----select the results file path---then select
graphs
Graph facilities menu-----select zones: Zone list (select
the zone name) and exist
Return to Time: var graph menu ----select time series plot
menu
Select Temperature— select zone db T----select draw graph 
The temperature via time graphed for the selected zone (s)
I hope these steps satisfying your request.
Regards

Alaa

Hi Dear Dr. Alaa,

I hope that you enjoy your trip to Iran.
Thanks alot for your complete answer.

I add PCM in my model. I use the Case600 ASHRAE140 for that.
Now I want to simulate. I want to have a inside temperature (for the main
zone).
I go to the simulation, but I can't do that.
It is very useful for me if you help me.

Thanks alot and again.

Best,
Helia
